To all whom, t may @o7/wenn.'

Beit known that l, CHARLES E. SANDSTROM, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Sawing-Machines, which is fully set forth in'the following specification, reference being had to the accompanying drawings, in which-LA l Figure lis a front elevation of my machine arranged to make three verticalcuts. Fig. 2 is a plan viewof the machine arrangedfas in Fig. l. larged scale, on the line 3 3 of Fig. 2. Figa is a section showing thefeeding mechanism on the line 4 of Fig. 2. Fig. visa rearelevation ofthe machine in section, on-an enlarged scale, on the line 5 5'of Fig. A3. Fig. 6 is a front elevation of the machine arranged to make a single oblique cut. Fig. 7is a side l elevation of the feeding mechanism. Fig. 8

is a sectional view of the feeding mechanism on the line S 8 of Fig .4. Fig. 9 isa rear elevation of the feeding mechanism, and Fig. 10 is a detail' view showing the guide in position for holding` the parts o f the moldingv apart after they have been sawed.

My invention relates to an improved sawing-machine designed for yuse principally iny sawingk moldings of that class where apiece of material is formed so as to constitute when properly split two or more pieces. The' ordinary form of molding upon which I have de.- signed this machine to operate consists of a duplicate design which when sawed in two makes two separate moldings of the same design, and in sawing these it is necessary to saw them at different angles, owing tol the different designs. My invention is designed to be placed in im mediate proximity to the molding-machine, so that a strip of molding from the machine will pass directly to the sawing-machine and there be sawed into the two pieces.

My machine consists of three principal parts-the feeding mechanism for feeding the strip received from the molding-machine to the saw, vthe guiding mechanism, which can be adapted to receive moldings of any desired shape and support them directly up t0 the saw, andthe sawing mechanism proper, which is arranged so that it can Fig. 3 is a vertical section, on aneu-V be adjusted for any desired position. v

The frame of the machine is of a generallyrectangular shape and -is supported by the four legs A, carrying the ysides and one of the endpieces A', which support the flat top 'A2, which may be metallic', but'which Ipreferably make of wood,'and'hold it in place on 'the' sides by the cleats d2, (seenin Fig. 5,) so that it is readily removable.

casing next to the molding-machine,- and in an arm A4, projecting from the left-hand side of the machine, is arranged a shaft B, which lcarries the belt-wheel B, by which the feeding mechanism is operated. f This belt-wheel B yis preferably operated by 'a belt from the moldingemachine, as it is desired that the vmolding .and sawing machines shall be operated'in unison andinconnection withreach other. A'gear-pinion B2 is also Vfastened upon this shaft B andmeshes with a gear-.wheel-C, upon theend of the shaft C, which is jour- The otherend ofthe rectangular box is formed by the plate naled in bearings D., whichmaybe supported by the endjplate A in any desired manner, but which .l have shown as cast integral therewith. The bearings Dare in the two'vertical plates D and D2of the shape best shown in Figs'S, 8,'and 9, which areconnected by the metallic plate D3, which maybe integral therewith or otherwise fastened thereto. In the upper portion of the plates D' and D2 are `arranged, the bearings D4, which are directly above the bearings D and contain the shaft E. The shafts C and E, respectively, carry the smaller gear-wheels C2 and Ef, of the same size, meshing with each other, the shaft C thus communicating its motion to the shaft E. Y Pivotally mounted upon the shafts C and E, respectively, just outside of the bearings Dvand D4, are thev frames Cand E2, which consist of the arms C4 and E3, respectively, which are united at their middle portions by the T-shaped bars C5 and E4, respectively.

Journaled in the bearings C6 and E5, respec-l IOO wheels C2 and E, respectively, thus transmitting the motion of the shafts C and E to the shafts F and G, respectively. These shafts F and G terminate at their inner ends in the feed-rolls F2 and G2, which are ofthe same size and one of which, G2, is preferably rubber coated. These feed-rolls may contact through an aperture A2 in the top A2 of the casing. These rolls are adjustable to any desired position relative to the top A2 and distanced apart by means of set-screws, one of which, C7, is mounted in the lug C8 and takes against the cross-piece C and the other of which, E6, is mounted in the cross-piece E4 and takes against the plate D2. It will readily be seen from this construction that the feed-rolls F2 and G2 are moved in unison to feed any molding which may be passed between them toward the driving mechanism and saw. It will also be seen that the frame E2 and its feed-roll G2 may be swung back out of the way, as indicated by the dotted lines in Fig. 4, whenever it is desired.

The guiding mechanism (best shown in Figs: 2, 3, and 5) consists of a framework composed of two vertical plates H, which are fastened Y by means of flanges H to the circular plate Q,to be subsequently described,and which are also supported by the cross-piece H2,which is fastened between the sides A. These plates H are connected attheir upper ends by the cross-piece H2.` A series of rods H4,whose upper surfaces are on the same level, connect the plates H and serve as a support for the lower guide-plates J, which are of the shape shown in Fig. 3. These lower guide-plates J consist of thin strips of metal, and as many of them are employed as maybe necessary for the width of molding which is operated upon. The upper set of guide-*plates J correspond to the lower ones, except that their shape is reversed, as clearly shown in Fig. 3. As above stated, these guide-plates J are'normally supported by the rods H4, and the guideplates J in turn are supported either directly or indirectly by the guide-plates J. In addition to these rods H4, however, the guideplates J are supported by the horizontal bearing-surfaces K and L of the plates K and L, which are pivoted on the rods K2 and L2, mountedin the plates H. These plates K and L are normally held with their horizontal bearing portions K and L supporting the guideplates J by means of the cam M, underlying the plates K,which are so shaped as to in turn support the plates L, as clearly shown in Fig. 3. This cam M is mounted upon the rod M', which has bearings in the plates Hand in one of the side frames A and terminates in an arm M2, just outside of the side frame A'. When the rod M is turned to the position shown in Fig. 5 and in dotted lines in Fig. 3, the cam M does not support the plates K, and through them the plates L, in their position where their horizontal surfaces K and L support the guide-plates J; but these plates K and L swing down about their pivot-rods K2 and L2, and their points K3 and L3 lift up the guide-plates J and through them the guideplates J. From this construction it will now be seen that ifa molding such as shown in Fig. 5 be placed upon the guide-platesJ when they are in the position of Fig. 3 and the guide-plates J be then placed upon the molding and the cam M be dropped the guideplates J will be carried up varying distances until their upper surfaces contact with the lower surface of the molding, while the guideplates J will fall down until their lower surfaces contact with the upper surface of the molding or of the guide-plates J, as the case maybe. While the guide-plates J arein this position they are secured by means of the clamping-plates N, which are controlled by the screw-rods N', threaded in one of the plates H and in the side frame A, and the fixed clamping-plates N2, which may be integral with but which are preferably adjustably secured to the other vertical plate H, as shown in Fig. 5. The upper guide-plates J are secured loosely between the plates O and O2, which correspond to theplates N and N2; but the guide-plates J 'are not clamped rigidly in position, as it is desired that they may be able to yield vertically, so as to accommodate any possible variation of thickness of the molding, and thusprevent any clogging or stopping of the feed. f To enable me to handle the guide-plates J as a body, l employ the yoke P,which terminates in the jaws P,which are preferably suitably roughened to increase the grip upon the guide-plates J. This yoke 1s supported byl means of the screw P2, carried` in the screw-threaded lug Pandoperated by the hand-wheel P4 to raise or lower the yoke P, as may be desired.` To control the jaws of the yokeP, I 4employ the bolt P5, passing through the arms of the yoke P and supplied with the nut P6, by the operation of which the jaws P" may be drawn together or apart, as may be desired.

The front portion of the framework of the machine is formed `mostly by the circular plate Q, which is rigidly fastened to the framework. This circular plate Q has a central opening Q' and serves as a bearing for an adjustable circular disk plate R, which is supported by and connected tothe plate Q by means of screw-bolts Q2, which pass through segmental slots R in the disk plate R and are adjusted as maybe desired in the screwthreaded holes Q3 in the front of the plate Q. It is desirable to adjust this disk plate R at any angle to the plate Q, and for this purpose a hand-wheel S is employed, which is mounted ina bearing on the rear of the plate Q and has a gear-pinion S', which meshes with a gear-wheel S2, mounted upon a shaft S3, having a bearing S4 upon the periphery of the plate Q and terminating in a pinion S5, which meshes with gear-teeth R2 upon a portion of the periphery of the disk plate R. The object of the construction now under description being to furnish an adjustable bearing for the roo IZO

saw or saws, it may be stated that while the construction so far described furnishes an adjustment whereby the saw can be placed at any desired angle it becomes necessary to employ mechanism whereby the saw can be adjusted at any desired position relative to the molding, and for this purpose I employ the rectangular plate T, which has bearings in the rectangular cut-away portion R2` of the disk plate R and upon the extensionl R4 of the said disk plate R. This extension R4 terminates in an outwardly-turned lug R5, in which is mounted a hand-wheel R6, carrying the screw R7, which takes into a screw-threaded bearing T upon the outer end of the rectangular plate T. Itwill thus be seen that by means of this hand-wheel R6 if the saws to be subsequently described are in the position of Fig. 1 they may be adjusted to the right or left, as may be desired, to cut the molding at different places, as may be desired. The position of the rectangular plate -T upon the extension R4 and in the bearing portion R3 of the disk plate R is maintained by means of the bolts RB, which pass through the slots T2 in the rectangular plate T and are placed in the holes R9 in the disk plate R or the extension R4, as the case may be. Mounted upon the raised ways T3 of the rectangular plate T by means of the channels U is the rectangular plate U, which carries the bearing-boxes V for the shaft W of the saw W. The position of this rectangular plateU upon the plate T is controlled by means'of the hand-wheel U upon the screw U2, which works in the screw-threaded lug T4 upon the plate T and has its bearings U3 upon the edge of the plate U, and it will be readily seen that by turning the hand-wheel U2 the plate U may be adjusted backward and forwarder up and down, as the case may be, to vary the position lof the saw W. The screw-bolts T5, passing through the slots U5 and into the guideways T3, serve to aid these guideways in holding the plate U in proper position relative to the plate T. A collar W2 is fastened upon the outer end of the shaft W' by means of the set-screw W2, and, acting against the outer bearing-box V, serves to hold the shaft W in place. A series of collars W4 are placed upon the lower end of the shaft W and are held in position by the nut W5 at the end of said shaft. By the employment of these collars lany desired number of saws may be employed, or the saws may be placed in almost any desired position relative to the end of the shaft. A pulley X is fastened to the shaft W between the bearing-boxes Vaud by it power is transmitted to the circular saw orsaws W.

In the operation of my invention the machine, as above stated, is set in proximity to the molding machine, so that the strip of molding therefrom may be fed by the feedrolls F2 and G2 directly between the guide-plates J and J', which are adjusted to the particular form of molding employed in the manner above described. The saw or saws are then adjusted by the three adjustments described so as to cut the molding in any manner which may be desired. In Figs. 1 and 2 I have shown three saws adj usted in vertical planes, so as to split the molding into four parts, while in Figs. 5, 6, and 10 I have shown a single saw adj usted to split the molding Y into two parts. In setting up the guide-plates J and J it is desirable to bring the pointed ends thereof out into as close proximity to the saw or saws as possible, and with the arrangement shown in Figs. 1, 2, and 3 it will beseen that all but six of the guideplates J and J are advanced into their outermost position, where the shoulders J2 thereof take against the cross-piece H5, fastened to the surfaces of the lian ges H and the arm H6, supported by the plate O2. The six guideplates J and J', referred to, are held back out of the way of the saws by means of the pins H7, which are passed through the holes vJ3 in the guide-plates J and J and holes in the lugs H8, formed in the ends of the plates H. When it is desired to employ a single saw in the manner shown in Figs. 5 and 6, it becomes necessary to set the guide-plates J and J somewhat dierently, but as many of them are set in their extreme outward position as can be without interfering with the saw, so that the molding may be supported as firmly as possible where the saw is operating upon it.

In order to prevent the weight of the upper strip of the molding that has been sawed pressing down upon the saw, especially when it is in a horizontal position or'substantially horizontal, as in Figs. 5 and 6, and thus causing it to bind, I employ an arm Z, which consists of ablade portion'Z, which is arranged in the plane of the saw WV, and the slotted shank portion G2, by which it is adjusted at any desired angle by means of the bolt Z3, passing through one of the inner segmental slots R and into one of the holes Q2. (Shown in Fig. 10.) The position of this arm Z is indicated in dotted lines in Fig. 2 5 but it would not be so positioned with the saws adjusted as in that figure. It is important that this arm Z be adjusted independently of the saw, inasmuch as it is necessary that it be employed to carry the weight of the part above the saw, and owing` tothe wide range of adj ustment of the saw it is possible that where the arm Z is in the correct position to support the material from the saw in one adjustment in another position of the saw a different relative adjustment of the arm will be necessary to support the material.

The saw or saws W are driven by a belt attached to any suitable source of power coperating with the belt-pulley X.

It will be seen that'myinvention comprises a sawing-machine that is capable of any desired adjustments, as well as a guiding mech- IOC IZO

anism, together with a set of adjustable feed rollers, allof which parts can be varied widely without departing from the scope of my invention. Therefore What I claim as new, and desire to cover by Letters Patent of the United States, is-
